WebGL Heatmap
A high performance WebGL/JS heatmap display library
webgl-heatmap is a browser-side rendering library that uses the GPU via WebGL to draw smooth, continuous heatmaps from large numbers of data points. Instead of relying on CPU-bound canvas operations, it leverages fragment shaders and additive blending to accumulate intensity and colorize results in real time. The API lets you push points or weighted samples into a buffer and then renders a gradient map where hot areas emerge organically from density rather than discrete markers. Because most work happens on the GPU, it scales well as the number of points grows and remains interactive for animations, live telemetry, or dynamic overlays. The library focuses on visual quality, producing anti-aliased, blur-free gradients that look good at various zoom levels and resolutions. It fits well into data-viz stacks where you need a responsive heat layer on top of maps, charts, or custom canvases, and it is compact enough to embed in dashboards and demos without heavy dependencies. -

jQuery.payment
Library for building credit card forms and validating inputs
Created by Stripe and archived on GitHub, jquery.payment is a small jQuery plugin that formats credit card inputs—numeric grouping, expiry dates, CVC—as you type and validates card numbers, expiry, and CVC with client-side checks. While deprecated in favor of Stripe Elements, it remains useful for legacy implementations. -

Angular Google Maps
AngularJS directives for the Google Maps Javascript API
Angular Google Maps is a set of AngularJS directives written in CoffeeScript and JavaScript for integrating Google Maps into AngularJS applications. This will generate source maps for development (angular-google-maps_dev_mapped.js) (non minified) and source maps to minified (angular-google-maps_dev_mapped.min.js) files. They each have their own corresponding map files. To get the coinciding source files you will need to copy the generated /tmp directory (currently not under scc). If you plan to hack on the directives or want to run the example, first thing to do is to install NPM dependencies. -

BuckyClient
Collect performance data from the client
BuckyClient is a HubSpot-provided JavaScript client that runs in the browser and collects performance data from clients, sending it to the Bucky server, which forwards metrics to endpoints like StatsD, Graphite, or OpenTSDB. It can automatically measure how long your pages take to load, how long AJAX requests take and how long various functions take to run. Most importantly, it's taking the measurements on actual page loads, so the data has the potential to be much more valuable than in vitro measurements. Modern browsers log a bunch of page performance data, Bucky includes a method for writing all of this in one go. It won't do anything on browsers that don't support the performance.timing API. Call it whenever; it will bind an event if the data isn't ready yet. -

Git Time Machine
Atom package that allows you to travel back in commit history
git-time-machine is a user interface (often as an editor plugin or UI extension) that allows users to browse a file’s history visually, stepping back and forth through revisions in Git like a “time machine.” It shows changes to a file over time, lets users compare older states, and often provides diff and blame views to understand how the file evolved. Instead of just opening a commit log or diff, git-time-machine gives an interactive, incremental experience where you can slide through versions and see content changes in place. This is especially helpful when diagnosing when bugs were introduced, exploring regression contexts, or reviewing code evolution visually. For projects with many commits, it accelerates historical exploration, and it is commonly integrated into editors so developers can use it in their working environment. -

Gulp-Cheatsheet
A cheatsheet for gulp.js
The gulp-cheatsheet repository is a compact, printable reference guide for Gulp.js, summarizing common commands, patterns, and usage examples in both JavaScript and CoffeeScript. It’s designed to be easily printed or posted beside a workstation, acting as a quick lookup for task definitions, streams, watching, and build workflows. The cheatsheet covers essential topics like Gulp installation, defining tasks, piping streams, watchers, and handling asynchronous tasks. It includes multilingual PDF versions (English, Japanese, Chinese) so users around the world can use it in their preferred language. The repository is lightweight (mostly documentation and examples), licensed under MIT, and maintained as a community reference rather than a full tool or plugin. -

Morris.js
Pretty time-series line graphs
Morris.js is a JavaScript charting library designed to render “pretty time‑series” graphs. It offers a very simple API for building line, bar, area, and donut charts, making it easy to add visually appealing charts to web pages. It is built on top of jQuery and Raphael.js. You'll need Node.js. I recommend using nvm for installing Node in development environments. Additionally, Bower is required for retrieving additional test dependencies. With node installed, install grunt using npm install -g grunt-cli, and then the rest of the test/build dependencies with npm install in the morris.js project folder. -

PleaseWait.js
JavaScript library to display customizable splash/loading screens
PleaseWait.js is a minimalist JavaScript library for showing splash-loading screens during the initialization of single-page applications (SPAs). It allows developers to define background colors, logos, and HTML content (like spinners) while delaying the main UI presentation. Once content is ready, it removes the loader and reveals the app. Installable via npm, Bower, or CDN. -

Pretty-Error
See node.js errors with less clutter
pretty-error is a Node.js library that renders JavaScript error messages in a cleaner, more readable, and visually styled format to make debugging easier. PrettyError turns error objects into something similar to an html document, and then uses RenderKid to render the document using simple html/css-like commands. This allows PrettyError to be themed using simple css-like declarations. There are a few methods to help you customize the contents of your error logs. You can customize which trace lines get logged and which won't. -

QuoJS
Micro #JavaScript Library for Mobile Devices
QuoJS is a lightweight JavaScript library aimed at building mobile-first web interfaces with a focus on touch interactions and simple DOM utilities. It provides a compact, jQuery-like API for element selection, traversal, and manipulation, but trims the surface area to keep payloads small for mobile browsers. A core feature set centers on high-level touch gestures—such as tap, double-tap, swipe, pinch, and long-tap—abstracting away platform quirks so developers can attach handlers consistently across devices. The library embraces modern browser features and CSS3 where available, offering helpers that make common mobile UI patterns feel responsive and fluid. Because it is intentionally minimal, QuoJS plays well as a drop-in alongside other client libraries when you only need fast gestures and a few utilities rather than a full framework. Its API is designed to be readable and chainable. -

Shadowsocks-Nodejs
Node.js port of Shadowsocks
Shadowsocks-Nodejs is a Node.js implementation of the Shadowsocks proxy protocol, providing server and client components that let users create an encrypted proxy tunnel to bypass network filtering and protect traffic in transit. The project reimplements the lightweight, stream-oriented Shadowsocks protocol in JavaScript so operators can run servers and clients using Node.js environments rather than native binaries or Python ports. It exposes typical Shadowsocks features such as configurable ciphers, listening ports, and worker process models that let operators tune performance for their deployment. Historically, the Node.js port has been used when convenience or platform compatibility mattered, though some maintainers and users note that performance and memory characteristics differ from other implementations. The codebase includes CLI helpers and configuration parsing so it can be run as a service or embedded in other Node.js tooling. -

Sticky-Kit
A jQuery plugin for creating smart sticky elements
Sticky‑Kit is a jQuery plugin that enables elements on a web page to smartly “stick” within their parent container during scrolling, ensuring visibility and preventing overlap with other page elements like footers. See the homepage for directions and examples. Include sticky-kit.js after you've included jQuery on the page. Ensures sticky items never overflow or obscure container boundaries (“bottom out”). Can stick multiple elements simultaneously. -

Stitch
Stitch your CommonJS modules together for the browser
Stitch is a library that simplifies the packaging of CommonJS modules for use in the browser. It allows developers to write modular JavaScript code using the CommonJS format and then bundles it into a single file that can be served client-side. This helps bridge the gap between Node.js-style development and browser environments, particularly before modern bundlers like Browserify and Webpack became widespread. The library automatically resolves dependencies, inlines modules, and ensures they can be required in the browser as if they were running in Node.js. It was designed to encourage clean modular design in front-end applications and reduce reliance on global variables. Stitch is lightweight and intended for developers who want a simple way to bundle JavaScript modules without a lot of configuration overhead. -

Talk-OS
Open source version of jianliao
talk-os is an open-source team chat platform that delivers real-time messaging, channels, and file sharing for collaborative work. It organizes conversations into public rooms and private groups, supports mentions and notifications, and provides a persistent message history with search so teams can catch up quickly. The system is designed around live updates, pushing new messages and presence changes to connected clients without page reloads. File attachments, emojis, and basic rich content previews make day-to-day communication more expressive while keeping the interface clean. Because it’s self-hostable, organizations can run it on their own infrastructure and customize authentication, integrations, and UI behavior to match internal policies. Its architecture demonstrates a typical modern chat stack with a JavaScript front end and a real-time backend, suitable for small companies and hobby teams that want Slack-style workflows without a hosted dependency. -

Tourist
Simple, flexible tours for your app
Tourist is a small library for building guided, step-by-step tours inside web applications, letting developers create interactive walk-throughs that highlight UI elements and explain workflows to end users. It provides a simple API for defining a sequence of steps, each tied to a DOM selector or screen area, with configurable titles, descriptions, next/previous controls, and optional callbacks for custom behavior. The library is designed to be flexible: steps can be triggered programmatically, attached to single-page app routing, or displayed conditionally based on user state, making it suitable for onboarding, feature discovery, or contextual help. Tourist aims to be framework-agnostic so it can be integrated into plain JavaScript projects as well as React, Vue, or other frontend stacks with minimal glue code. It also supports common niceties like mobile-friendly positioning, step-skipping, and hooks for analytics events so teams can measure adoption of guided flows. -
20
Turbolinks Classic
Classic version of Turbolinks
Turbolinks Classic is a now-deprecated JavaScript library (largely used in Rails projects) for speeding up navigation by intercepting link clicks and replacing only the <body> and page title instead of reloading the entire page. It avoids recompiling JS and CSS on each navigation, improving perceived performance. Turbolinks makes following links in your web application faster. Instead of letting the browser recompile the JavaScript and CSS between each page change, it keeps the current page instance alive and replaces only the body (or parts of) and the title in the head. Think CGI vs persistent process. -
21
Vim-Mode
Next generation vim support for atom
vim‑mode is an Atom editor package providing modal Vim-style editing—combining the power of traditional Vim keybindings with the extensibility of the Atom editor. It’s now deprecated in favor of vim-mode-plus. Provides Vim modal control for Atom, blending the best of Vim and Atom. Seamlessly integrates with Atom's UI and editing workflows. Easy to install via Atom’s package manager. -
22
jQuery Shapeshift
A dynamic grid system with drag and drop functionality
jQuery.shapeshift is a jQuery plugin that creates dynamic, Pinterest-style column grid layouts with drag-and-drop functionality and predictable indexing for each item. Rearrange items within a container or even drag items between multiple Shapeshift-enabled containers. Dragging elements around will physically change their index position within their parent container. When a page reloads, as long as the child elements are placed in the correct order, then the grid will look exactly the same. Shapeshift uses jQuery UI Draggable/Droppable for help with the drag and drop system. Luckily, there is already a plugin called jQuery Touch Punch, which provides touch support for jQuery UI D/D. It can be found in the vendor folder. -
23
jQuery.Turbolinks
Plugin for drop-in fix binded events problem caused by Turbolinks
jQuery.Turbolinks bridges the gap between jQuery plugins and Turbolinks 1–4. It ensures jQuery event handlers rebind properly on page change, solving issues with uninitialized bindings after Turbolinks page swaps. Though deprecated (incompatible with Turbolinks 5+), its simplicity makes it valuable for older Rails apps. -
